I Am Astonished at this VERY minute but CRUCIAL detail that the engineers DIDNT include in the assembly of the 4t65e?My GXP has It?s 2nd Trans and at 25k miles, I?m getting Extremely QUICK temps of 210-220 all while the engine is at 120 MAX! The TCC starts Whining at about 215 and it?s slamming into 2-3rd and I?m blown away at this Underestimation of Components. Plus I REALLY think the shop that did the trans put a 4t65e, NOT the 4t65eHD! The serial numbers are NOT the same?So ima have a lil Chat with the Tranny Shop Boyz!Originally Posted by 02NavyBlue
I would also add that you should add a Sonnax differential lube line retainer, part# 84532-01K. The differential lube line is known to sometimes fall out since it has nothing holding it in, and has a rubber section of hose. It will cause excessive differential wear, and eventually failure of the differential. I bought a few and will always install one when I have the pan off of a 4t65e. They're very inexpensive, $1.96 +shipping on rockauto.
